TELH TelCom̴å¬ Telephone Extension Ringer Device

Federal Signal's TELH Extension Ringer Device is a vibrating horn which is activated by the ringing signal of a telephone system. This device is specifically designed for use with an analog telephone. The ringing signal of 40-150VAC, 16-60Hz and local 120VAC power is all that is required to activate a TelCom signal.

This TelCom device is intended to be mounted on a vertical surface such as a rigid wall or post. The TELH ringer has a three-conductor six-foot, 120VAC power cord extending from the unit. Connecting the TelCom device to the telephone network is accomplished by running a modular telephone line cord (RJ11) to an existing jack or a duplex jack (customer supplied) into an existing modular jack. The TELH is designed with a durable zinc diecast housing painted with gray powder coat enamel, and features an internal solid-state relay.

Telcom devices are designed for high ambient noise areas such as manufacturing facilities, machine and sheet metal shops. They are also useful in large open areas such as a warehouse, loading dock or a large office.

This fourinch Vibratone horn has a decibel output of 100dB @ 10` (110dB @ 1m). When an incoming call activates the TELH, it produces an electro-mechanical signal by vibrating a diaphragm.
